Another way to move your DDC files to another location if you don’t want to mess with the config location is to simply create a junction or shortcut to another drive/location. Just move the whole folder “C:\Users<your user name>\AppData\Local\UnrealEngine” to a new location for me I put it on my second SSD drive root so I now have “F:\UnrealEngine” then just create a shortcut to the new location in “C:\Users<your user name>\AppData\Local”
This moves not just the common DDC but potentially any other engine version specific files over to that same location, if you want to remove old engine version or common DDC files you can just go into F:\UnrealEngine and remove them there.
You can use the same trick for moving your VaultCache for the Launcher to a new location as well.
Also you can use a Junction instead of a shortcut, but most people are not comfortable with command line operations and batch files, so typically prefer Shortcuts and I think they basically the same thing, but for those interested you can use a batch file command like this to achieve the same result
mklink /j C:\Users\deanb\AppData\Local\UnrealEngine F:\UnrealEngine
Hope that helps.
This worked perfectly for me. Moved my UnrealEngine folder, created a shortcut, deleted original folder and replaced it with new shortcut. All projects open fine, 42 GBS saved on my C drive, thanks.
